In the night’s main event, former heavyweight champion Junior dos Santos clashed with the red-hot Ben Rothwell. The Brazilian dos Santos looked to rebound from a second-round TKO loss to former Strikeforce titleholder Alistair Overeem in December. The 32-year-old had alternated wins and losses since 2012. Rothwell, meanwhile, entered the contest having won four straight and five of his last six. All five wins had come via finish, including a guillotine choke submission of Josh Barnett in January.

More heavyweights were in action in the night’s co-main as former title challenger Gabriel Gonzaga took on the hard-hitting Derrick Lewis. The submission ace Gonzaga snapped a three-fight skid in December with a decision win over Konstantin Erokhin, while Lewis picked up his second straight finish in February, stopping Damian Grabowski.
